Fixed inductors are electronic components designed to store energy in the form of a magnetic field. They are also referred to as inductors, chokes, coils or reactors, and are used for transmitting information, in filtering circuits, and for coupling purposes.

The 2000-4R7-H-RC is a fixed inductor that is designed to capture and transfer energy in the form of a magnetic field. This inductor is manufactured by a combination of copper wire and high-permeability ferrite core. The copper wire is wound around the ferrite core in a fixed arrangement, with the inductance being a function of both the physical structure and the ferrite material.

The 2000-4R7-H-RC fixed inductor has an inductance range of 4.7 - 20mH, a DC current range of 0.150 - 0.470A and a DC resistance range of 2.2Ω - 4.4Ω. It features a lead wire length of 0.30m and an operating temperature range of -40°C to +125°C. Additionally, the 2000-4R7-H-RC is RoHS compliant.

The 2000-4R7-H-RC inductor has a wide range of applications including DC-DC converters, switching power supplies, switching regulators, and battery chargers. The high stability and reliability of this inductor make it suitable for a variety of power management applications. The 2000-4R7-H-RC also has excellent heat dissipation characteristics, allowing it to be used in high-power applications.

The working principle of the 2000-4R7-H-RC fixed inductor involves the creation of a magnetic flux when a current is passed through the copper wire. This magnetic flux links with the iron core of the inductor, creating an electromagnetic field that is proportional to the current.

The 2000-4R7-H-RC operates on the principle of self-induction, which states that the magnitude of the generated field is proportional to the rate of change of the current. Thus, the induced voltage increases as the rate of change of the current increases. As a result, when a current flows through the 2000-4R7-H-RC, an electrical voltage is generated within the inductor, creating a magnetic field around it.

As the current through the 2000-4R7-H-RC increases, the magnetic field created within the inductor increases, resulting in a greater resistance to the further increase of the current. This resistance to the current increase is known as inductive reactance and is measured in ohms. As a result, the 2000-4R7-H-RC acts as an AC current limiter, allowing only a certain amount of current to pass through it.

The 2000-4R7-H-RC fixed inductor is a highly reliable and efficient component that is suitable for a wide range of power management applications. It features an inductance range of 4.7 - 20mH, a DC current range of 0.150 - 0.470A, and a DC resistance range of 2.2Ω - 4.4Ω. Additionally, it has excellent heat dissipation characteristics and operates on the principle of self-induction, using magnetic flux to generate an electromagnetic field in response to current flow.
